What (state,city or country) have you visited that was most fascinating to you?

For me, I would have to say Toleda, Spain. I loved the narrow streets, the old eateries with Spanish Ham hanging in the window, the architecture and the views - it's almost as if it took me back into time. I kept wondering how it would be to live there every day - maybe the city folk all knew each other. A romantic thought I'm sure. I was there when I was 18 years old; it's been 20 years since then, but it was so incredibly memorable. I hope to go back one day soon.

So then I ask you; what (state,city or country) have you visited that was most fascinating to you?
